Description

All year traction tire stud system

Many attempts have been made to solve this problem, but most systems do not function properly over time due to the significant wear and tear that the stud device must withstand while driving. Some adjustable stud systems require air pressure to allow the studs to come in and out. Unfortunately, these systems do not function effectively. When the studs are pressed against the road surface, the air tends to be compressed. Therefore, the studs enter the tires again. In the case where air enters the hose of the vehicle brace system, a similar effect occurs due to insufficient pressure. Other systems require studs to penetrate the tire casing. This is considered to be very unreasonable to the person skilled in the art because the tires are separed in a short time since the steel belts are corroded due to large friction and wear and cracking. Other known moving stud systems are those where the studs are too large, too complex, expensive or susceptible to sandy water, frost, shock, etc. and consequently easily damaged, broken or worn out too quickly. It is made up of elements and is not practical.

Norwegian patent application 861224 discloses a stud device consisting of a movable wall which is combined with an inner wall of a tire to form an air chamber. As a result, the problem described above has not been solved by this system, since this system is based on pneumatics and needs to penetrate the tire casing. German Application Publication Nos. 2602544 and 1680491 and US Pat. Nos. 3,766,956, 3,340,921 and 3,095,918 are all similarly based on using air or need to penetrate the tire casing, thus solving the above-mentioned problems. It remains. In addition, such movable stud type devices often require more space. In addition, placing the movable studs under or within a tire tread typically requires a significant tread thickness. A thick tread tends to heat up the tire and consequently reduce running performance.

Iceland Publication No. 131970 also discloses a pneumatic based moving stud system and has all the above mentioned disadvantages. Moreover, such a system in which the hose rotates at high speed inside the tire is at risk of bursting (the tire is flat tire). In addition, flat tires may damage the stud system.

US Pat. No. 2,941,566 uses fluid to move the studs, but needs to penetrate the tire casing, leaving the above-mentioned problems unresolved.

BACKGROUND OF THE INVENTION The present invention relates to a movable tire stud system that can adjust tire studs while driving or stopping a vehicle, thereby helping to quickly solve problems related to running on slippery or ice covered roads.

Experiments have shown that the stud system of the present invention has several advantages. First of all, compared to the pneumatic and hydraulic systems of the prior art cited because the sipe is combined with a stud jack mounted on the shoulder of an unprocessed tread block and the structure of the system of the present invention is similar to the brake system of a vehicle. Durability is great. When the brake pedal is pressed, the piston in the brake cylinder is pushed against the brake shoe. In the present invention, the tire stud is pressed against the road surface by an equivalent action force. Another advantage is that unlike hydraulic or pneumatic systems, they do not leak and are more durable against bumpy road surfaces. The adjustment of the studs can also be made in a simple manual way via the handle.

Unlike the publications described above, the studs of the present invention are mounted on a very large shoulder block that does not penetrate the tire casing and does not have a sipe of the tread. The stud may be mounted at a position other than the tire tread if, for example, tire tires allow tire dimensions. Considering the system of the present invention for smaller vehicles, there are few tires with tread shoulder blocks of the required dimensions. However, such a tire can be manufactured. Some rugged terrain tires have a sufficient tread thickness to mount small moving studs without penetrating the tire casing. Further development can improve the adaptability of these stud systems.

In practice, a functioning movable stud system is rarely required. Such a system offers vehicle owners the convenience of not having to change tires or use chains each spring and autumn. Traditional stud systems wear out and wear out quickly throughout the winter, but the sharpness lasts longer because movable studs are not used often. Sharper studs mean improved driving safety. Studs that are used throughout the winter mean that road maintenance is expensive and increases air pollution. Since static studs are used throughout the winter, they should be smaller than movable studs to reduce road wear. As a result, those skilled in the art point out that the moving studs may protrude more than the traditional static studs, resulting in a significantly reduced braking distance on ice-covered roads, especially compared to tires without studs. There is no alternative but to use tires with studs that are generally in good condition when driving when new snow falls on an ice covered road.

As a result, there is a clear need for a movable stud system such as the one proposed herein. This need is met by a stud system of the type defined in the appended claims.

The stud system according to the present invention is described more strictly with reference to the embodiments with reference to the enclosed drawings.
